Optics Prism desperately need help optics question?
Light is incident on an equilateral glass prism at a 45.0 degree angle to one face. Calculate the angle at which light emerges from the opposite face. Assume that n=1.58.
Equilateral glass prism of 60 degrees between the glass surface.
So at 45.0 degree incidence on one glass surface, using sin 45 / sin r = 1.58, r = 26.6 degrees. This ray will hit at the second surface at an incident angle of 33.4 degrees. But at the 2nd surface, this light will bend away from the normal, since it is travelling from glass into air.
so at the second glass-air boundary,
sin i(the angle in air) / sin 33.4 = 1.58
i = 60.5 degrees. (the angle which emerge at the 2nd surface)

optics !!!!!!!!!!!!!!!!!!!!!!!!!!!?
a thin prism of angle 5 degrees is placed at a distance of 10 cm from object. What is the distance of the image from the object ? (given refractive index of prism=1.5)
Hello Mukhul, the question is so abstract and ambiguous. Please give it in the right sense.
In order to develop excellent photonic devices, we have to fully understand the physics behind operations of photonic devices. This book thoroughly teaches the fundamental physics currently applied to the development of photonics devices such as energy ba

Two upright 0.85- m-tall plane mirrors are placed parallel to each other 2.80 m apart. The top of the mirror on the right is then moved back a little so that its surface tilts away from the other mirror at an angle of 10.00° off the vertical. A narrow laser beam passes perpendicularly through a small hole in the very bottom of the mirror on the left. It subsequently strikes the tilted mirror from which it reflects. How many times will it reflect off the upright mirror on the left?
Not even once. This is so because tan^-1(0.85/2.80) = 15.94 degree
The angle between the first incident ray and reflected ray from the tilted mirror will be 20 degree. hence the reflected ray will miss the upright mirror.
Astronomical Optics and Elasticity Theory provides a very thorough and comprehensive account of what is known in this field. After an extensive introduction to optics and elasticity, the book discusses variable curvature and multimode deformable mirrors,
The book covers all theoretical aspects of modern geometrical charged particle optics. It is intended as a textbook for graduate student and as a guide for researchers, who are involved in the design of electron optical instruments and beam-guiding system
This book is the culmination of twenty-five years of teaching Geometrical Optics. The volume is organised such that the single spherical refracting surface is the basic optical element. Spherical mirrors are treated as special cases of refraction, with th
In the 50 years since the first volume of Progress in Optics was published, optics has become one of the most dynamic fields of science.

SMALLab Optics: Mirror Playground Test
can someone help me with my science homework on optics please?
1. Imagine that a small lamp is placed at the principal focus of a concave mirror. What would be the nature of the reflected beam? Give an example of a practical use of this fact.
When an object is at the focal point all light is reflected as parallel rays.
A car headlamp uses this. The bulb is at ( or near) the focus so that the light from the bulb moves as an approximately parallel beam rather than spreading out in every direction.
This keeps the light bright where we need it and avoids light going where we don't want it ( other drivers eyes)
The ScorpiusD Series a portable diode laser emitting at 808nm produces a completely invisible laser beam. Extreme caution must be used when operating any infrared laser as the human eye will not detect it. Laser safety goggles are included with each Scorpius Series laser. The ScorpiusD Series is available at up to >1.0W much greater output power levels than those available in visiblewavelength portable lasers. In addition the price per milliwatt of output power is a fraction of the cost of visible lasers. Ideal for IR laser experimentation such building a 532nm laser using Nd:YVO4 and KTP crystals to produce green laser light at 532nm.

Temperature Laser What temperature should my central air conditioner be putting out of my vents?
My central air conditioner is a Trane XE1000. During these hot days the temps sometimes run mid 80's to low 90's outside. My unit is almost running constantly and I have it set at 72 degrees. What should the temperature be coming out of the ducts at the floor level. I took a laser temperature and it was running in the mid to high 50s but yet the unit is running like crazy and in my opinion not cooling the house like it should. Last week when it was in the low 90's the house was a balmy 77 degrees inside only getting to the set 72 later that night. Is this normal or should I have it checked??
This sounds about right. What you have is a 20 degree temperature drop that you are pushing your AC to provide. Because of the higher temps and the lower setting on your T-stat, it will continue to run until the temperature is met. With opening doors or exposed windows, this will be hard to do when the sun is out. With cooler temps at night time, the unit "catches up" to your thermostat.
If you haven't had maintenance on it yearly, I would suggest getting it cleaned by a certified tech. Your evaporator coil could be dirty, causing less cool air to be blown into your vents.
